Eligibility

Inclusion criteria:

• Participant must be 20 to 50 years of age inclusive, at the time of signing the informed consent.

• Japanese participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring.

• A Coronavirus Disease-2019 (COVID-19) screening with negative test: Two consecutive approved molecular tests (Polymerase chain reaction [PCR] or antigen test) separated by greater than (>)24 hours. The second test should be within 72 hours of admission to the unit on Day -1.

• Body mass index (BMI) within the range 18.5 to 24.9 kilograms per meter square (kg/m^2) (inclusive).

Exclusion Criteria:

• History or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study treatment; or interfering with the interpretation of data.

• Active infections (including localized infections), or history of recurrent infections (excluding recurrent fungal infections of the nail bed), or has required management of acute or chronic infections

• History of any respiratory disease which (in the opinion of the investigator) would compromise participant safety or the ability of the participant to complete the study.

• Clinically-significant or unstable (in the opinion of the investigator) persistent cough or dyspnea that is unexplained.

• Current or previous active Tuberculosis (TB), history of untreated or incompletely treated active or latent TB, suspected or known extra pulmonary TB.

• Previous close contact with a person with active TB and did not receive satisfactory anti-tuberculosis treatment as per World Health Organization (WHO) or national guidelines.

• Hemoglobin less than or equal to (<=)9 grams per deciliter (g/dL); white blood cell (WBC) count <=3.0 times 10^9/ Liter (L); platelet count <=100 times 10^9/L; absolute neutrophil count (ANC) <=1.0 times 10^9/L; lymphocyte count <=0.75 times 10^9/L at screening.

• A vaccination (live or attenuated) within 30 days prior to Day 1 or Bacillus Calmette-Guerin (BCG) vaccination within 365 days prior to Day 1, or a live vaccination planned during the course of the study. Any COVID-19 vaccination within 14 days prior to enrolment.

• Any surgical procedure, including bone or joint surgery/synovectomy within 8 weeks prior to Day 1 or any planned surgery within the duration of the study.

• Significant allergies to humanized Monoclonal antibody (mAb).

• Participants with known COVID-19 positive contacts within 14 days prior to screening.

• History of lymphoma, leukemia, or any malignancy.

• History of infected joint prosthesis at any time, with the prosthesis still in situ. History of leg ulcers, catheters, chronic sinusitis or recurrent chest or urinary tract infections.

• Use of prescription or non-prescription drugs within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) before the start of study intervention until completion of the evaluation visit, unless, in the opinion of the investigator and sponsor, the medication will not interfere with the study.

• Treatment with biologic agents (such as mAb including marketed drugs) within 3 months or 5 half-lives (whichever is longer) prior to dosing.

• Blood donation/sampling within 60 days prior to screening.

• The participant with positive Serological test for syphilis, Human immunodeficiency virus (HIV) antigen/antibody, or Human T-cell lymphotropic virus type 1 (HTLV-1) antibody.

• The participant with positive test for Hepatitis B surface antigen (HBsAg), Hepatitis B core antibody (HBcAb), Hepatitis B surface antibody (HBsAb), or Hepatitis C virus (HCV) antibody.

• Positive pre-study drug/alcohol screen.

• Participants with signs and symptoms suggestive of COVID-19 (fever, cough) within 14 days prior inpatient admission on Day -1.
